Solidworks has its own native format which is .SLDPRT

The STL or a Step file is the best thing he will be able to import.

I believe I can export a sldprt file, but they are version specific if I remember correctly.

I have already printed a few of the parts and they look pretty solid. I plan on doing something a little different for y axis but it would be awesome if i had existing part files to work from with correct dimensions.
Apperently I can import a solidworks file, but I can't export to one. What other formats can you use?

Just waiting on t nuts for the build but here's the rail so far. I made some printed spacers and a belt stabilization bar as well.

Attached are the 2 spacers for the mounting plate. 6mm spacers for the wheels and 24mm spacers for the larger spacer. You would need 6 and 2 spacers respectfully if you use the 6 point mounting plate like mine otherwise 4 and 2.

Any chance of the inventor files so I can look at the assembly?

They are kind of big at this point, so you would need somewhere for me to upload them to. Pm me if you have a spot you would like them uploaded to.

The layout assembly of the parts in the file tend to be somewhat chaotic. I tend to just design the part where it sits and test fit a physical object rather than drafting the whole assembly out.

I'm having a look at the models to see what I need to modify for the replacements I found for your heat inserts. I recognised you are using M5x11 heat inserts for the motor mount, but the holes are only 9mm deep. On the other side, the holes for M5x6 inserts on the Right X end are 8mm deep which seems to make sense.
A mistake in the motor mount bracket or intention?

I will have to source my parts from all over europe, but in the end it should be an Openrail-TAZ :lol:

The motor mount block is designed so that the lower piece of the insert is buried in the plastic. Ordinarily you would want a deeper hole. I wanted to make sure the motor inserts dont pull out under strain. So far they seem to work well. The side inserts are the shorter ones.

The Openrail_square_backplate_1_0_a.stl does not work without modification. The added 2 arms knock on the motor mount just the one side though.
